Columbia is developing technologies that will
generate energy between one and three miles offshore - where the
available wave energy
is greatest. We believe that direct drive systems, which avoid the
use of pneumatic and hydraulic conversion steps, are more efficient,
more reliable and easier to maintain, and are therefore the most
likely to deliver the lowest cost of energy. Our research path
focuses on:
- Point absorbers
- Direct coupling of the wave motion to the generator
- Innovative use of permanent magnets and other highly-efficient
components
- Reducing the number of moving parts
- Minimizing the number of conversion steps and associated losses
